Patent GB-2215176-A (GB)
Title: Lawnmower
Inventor: DIXON JOHN
IPC: A01D34/82
Filed: 1988-02-15
Abstract: A substantial reduction in noise generation from a ride-on lawnmower is achieved by forming the cutter head with a central disc and protuding blades each with a forward cutting and an upwardly turned rearward edge. Because the upwardly turned rearward edges of the blades increase of the blades the effective airflow, the cutter head can be driven more slowly and thereby, other things being equal, reduce engine and transmission noise. Surprisingly, the number of protruding blades on the cutter can be increased over the conventional number, and is, typically eight blades. Thus, by a combination of blade design, number of blades, and consequential speed reduction improved acoustic performance can be achieved for the same level of grass cutting and collection. The noise reducing charateristics can be supplemented by other conventional shielding, damping, and shrounding expedients.

Title: Digital filtering
Inventor: KLINE RICHARD B
IPC: H03H17/02
Filed: 1989-01-20
Abstract: A digital decimation fitter for receiving a stream of input digital samples at an input sample rate, and for delivering a corresponding stream of output digital samples at a different output sample rate stores a plurality of input digital samples, derives samples of the output stream from the stored input digital samples, and makes an output sample available for inclusion in the output stream at all times, whereby the output sample may be delivered with a selectable phase. An analog-to-digital converter has a sigma-delta modulator for generating a high rate stream of digital samples of an analog signal at a rate substantially higher than the Nyquist rate, and a digital decimation filter for receiving the high rate stream and delivering a corresponding stream of filtered output digital samples at a lower rate, the decimation ratio being selectable. A multiple-mode modem for use with a channel on which a carrier may be modulated in accordance with at least two different possible modulation schemes, receives the modulated carrier from the channel and converts it to a corresponding stream of digital samples, whereby different receive filters applicable to different modulation schemes need not be provided ahead of the analog-to-digital converter. <IMAGE>

Title: Continuous extrusion of pre-heated billets
Inventor: PEDLEY ROGER
IPC: B21C23/08
Filed: 1990-11-06
Abstract: In a method of Operating a Continuous Extrusion Machine it is well known to continuously extrude metals, particularly aluminium and its alloys, in a continuous extrusion machine known as a Conform machine. Conventionally cold metal stock bar is fed to the machine which, by friction. heats and pressurises the metal until it can be forced through an extrusion die. Attempts to extrude small cross sectional area products from large cross sectional area stock bar result in unacceptable power consumption, undesirable changes in the metallurgical properties of the product and low productivity. The present method involves preheating the stock bar to in excess of 200 DEG C before extrusion enabling small cross section (16mm<2> to 800mm<2>) extrusion to be produced from large section (1000mm<2> to 1300mm<2>) stock. The extrusion product does not require further metallurgical treatment to produce a finished product.
